Mike:
I was able to get a couple of the Zinkowski Nerines way back. I grew them under HID lights and the actually flowered. They now sit in a brand new greenhouse.
One is pushing up a scape. It's the one called Blanchfleur.
I believe there is a picture on the Wiki of it.
My experience with them is that they are very tough bulbs and given the minimum care they'll flower.
